Functional window that I do not have.

Colleagues, please tell me the answer to my question!

I saw a video on Youtube about a gentleman calibrating the Z axis with an electric contact sensor.
And at the same time, he used a feature window in his EMC2, which I don’t have at all.
And the "Touch off" button is highlighted and pressed.

Here is the link to this video - LinuxCNC manual tool change with tool length offset

How did he get this functionality? When installing, do you need any additional spells to speak?
Tell me, please, where do they get this page? Maybe there are still some?

Thank you in advance for your answers,
Ogogon.
